by declare that the following is a full, clear,

and exact description thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts This invention relates to means 'wlncn maybe associated with power driven machines, which machines are manually controlled, whereby the invention automatically actuates and controls the manual controls of the power driven machines so that said machines will. automatically perform anvidesired series of operat ons.

The chief object of this iIlVGIltlOlrlS to provide an attachment for the present manually controlled power driven machines such as lathes, screw machines and thedike, whereby the same n'iay be automatically controlled by said attachment after the at tachment has been adjusted to the particular machine to which the same has been applied and to the particular work to be performed thereby.

()ne objectof the invention 1s to make the attachment universally ad ustable to the several standard manually controlled power driven machines atpresent in use by the public.

A further object of the invention 1s to provide that the attachment'is adjustable tllti to the particular work to be perforn'led at any given time by the machine to which the same is attached.

The chief feature of the invention consists in adapting the attachment to standard manually controlled power operated machines without materially changing the construction of the same so that said machines may also be used when desisired as manually controlled power :lriven machines. Another feature of the invention is that the attachment wl'ienproperly adgusted permits one operator to watch a plurality of machines, said operator merely renewing the supply or stock to the machines when exhausted thereby and replacing worn out or broken. tools.

Another feature of the 1nrent1onconsists in the operating of the power driven machine at maximum speedat all times, whereby eliminating the fatigue element of the manual control, said feature being accomplished byspeed ing up the several parts upon the non-Working strokes of the various parts of the power driven machines.

Another feature of the inventiori consists in associating and connecting the same to the main power mechanism such that the attachment will automatically stop the attachment and alsostop the machines to which .thesame is applied, whereby said machines may be actuated to receive pieces of work which require work be performed thereon while the same is secured in the machine chuck, said operations being known aschuck jobs or chuck work. The foregoing arrangements permit one operator to position or secure one piece of work in the machine, start the same and pass on to other machines where the same work is repeated, the first machine automatically operating upon the ,work through a series of operations and stopping as indicated when said operations are completed.

Another feature of the invention consists in providing the attachment with means whereby the same may be manually operated, which permits the operator to adjust to a liner degreeof sensibility the variousopcrating cams and associated parts than otherwise would bepossible were the attachment to be power driven as is done during the normal operating conditions.

A further feature of the invention consists in associating with the means for disconnecting the power actuation such that the attachment may be manually operated, additional means, Which means constitutes a safety device whereby, should for an reason the operating men'ibell's of the attachment become jammed, said safety dcvice disconnects the operating parts from the power supply.

Still a further feature of the invention is the construction 'of the attachment such that when attached to turret lathes and the like, wherein a six gang turretis provided, said attachment during oneo'peration thereof controls onecomplete revolution of the turret, such that on a single twotool, three tool or greater tool job, up to and including a six tool job, said attachment yes respectively cmnpletessix, three, two and one-complete piece of work for a single rev volution the main actuating part of the attachment.

The particular feature of the invention, when the same is attached to a power driven manually controlled turret lathe or the like. consists in automatically eontrollin g the feeding of the stock, the positioning of the same, the feeding of the material finishing tool, the feeding of the cutting olf tool, the feeding of the turret, controlling the movement of the turret, controlling the speed of operating all of the foregoing parts. controlling the speed of the lathe as well as generally controlling all'of the mechanical parts of the machine.

The full nature of this invention will be understood from the accompanying drawings and the following description and claims.

Fig. 8 is a front view of the same showing the parts as illustrated in Fig. 3.

.This invention relates to means for automatically controlling power driven machines which heretofore have been manually controlled. The invention consists in providing an attachment for machines of the character described, which attachment permits the machine to be operated at its maximum e'liiciency at all times irrespective of the personal element or fatigue of the operator. In the drawings the invention is illustrated as applied to a siX tool turret lathe in which 10 indicates the usual supporting frame, 11 the body, 12 the headstock, 13 the cross head slide, 14 the tool supported thereby, 15 the turret and 1.6 the turret slide. The turret lathe is driven by means of a pair of rcversibly driven pulleys 17 and 18, each of which is provided with the clutch members 19 with which is associated the clutch cone 20 actuated by a handle member 21, whereby the shaft 22 may be driven in either direction or may be held idle, as desired. The shaft 22 is suitably, supported as indicated and is-provided with a cone pulley 23 in stepped relation. Similarly the lathe is provided with a reversely positioned cone pulley 24, said last mentioned pulley being driven by the first mentioned pulley by means of the belt 25, all of which is of the usual construction.

In the present illustration the lathe is provided with a self centering chuck 2e supported by the head stock l2. The quick acting and self centering chuck 26 is controlled by means of the usual hand lever 27 and by the levers 28. Similarly the lathe is provided with the back gear controlling lever 29. It will be understood that the slide 13 is movable transversely of the axis of the lathe and the base 30 thereof is slidably longitudinally of the axis so that said slide and tool rest 14 may be positioned in the usual manner. The turret slide 16 is normally operated by means of the wheel 31. and, is moved longitudinally of the lathe axis. \Vithin the turret construction is suitable mechanism associated with the turret 15 whereby at the end of the rearward movement of the slide 16 upon the base 32, which as shown. may be adjusted in the usual manner upon the slide 33 supported by the body of the machine. said mechanism rotates the turret through the proper angle to position the next succeeding tool in position for the next operation upon the stock 34 engaged or supported by the quick acting chuck 26. All 0 1 the loregoing parts comprise the standard turret lathe, and to this lathe or similar machines the invention has been applied.

It will be understood that when the lathe is manually controlled the sequence of operation is as follows. The stock 341 is supplied to the quick acting and sell" centering chuck 2G, and said chuck is opened by means of the lever 27 and links 28 such that the stock, such as a bar or tubular material 3i is positioned therein. The support 32 is positioned adjacent the head stock to provide proper clearance for the cross slide as well. as the turret movement. The turret slide 16 is moved upon the body 32 by means of the wheel 31, and the tool 35 is positioned at the end. of the movement of the turret slide such that the same abuts the stock M to position the stock with respect to the self centering and quick acting chuck so that suliicient stock is exposed for subsequent operations. The turret slide is then withdrawn and in the usual practice, the cross slide 12 supporting the tool post ll; with a suitable tool 36 is moved transversely in the ordinary lathe construction by means of: a hand wheel not shown. such that the tool engages the tree and forward end of the stock 34 to finish the same as desired. The hand wheel controlling the movement ol the slide is then reversed and said. tool withdrawn from engagement with the stock. The wheel 81 is then actuated and the. tool 37 is positioned in place of the tool 35 and is moved longitudinally of the lathe into engagement with the stock 34-. After completing this operation the turret slide 16 is 1 wheel 31, is actuated by therefor a rock shaft withdrawn and another tool, if necessary 01' desired, positioned and moved into engagement with the stock 84. Heretofore turrets have been constructed preferably of five and six tool capacities and the invention is herein illustrated as applied to a six tool turret. Thus for each revolution of the turret 15 a one tool job will complete six pieces of work, a two tool job will complete three pieces of work, a three tool job two pieces of work and a six tool job one piece of work. It will also be understood that for a four and five tool job, two or one of the turret sockets will be blank for the complete operation of the turret, when the same is automaticallyactuated.

In the present invention the tool post 14 is described as being slidably movable .by the removal of the usual hand wheel actuatingthe cross slide 13 and substituting 38 supported in a bracket 39 positioned upon the body 11 of the lat-he. One end of said rock shaft is securedto the slide 13 by a'lever 40, while the other end of said said shaft is actuated by means of a lever or bar 41 which in turn .is actuated by means of a rod 42. Similarly the self centering chuck control lever 27 is actuatedby a link or rod 43. Similarly the back gear lever 29 is actuated by an actu ating bar or rod member44, while the turret slide. manually controlled by means of the an upright bracket 45 to which is adjustably secured the rod 46. To the usual turret slide controlling wheel 31 is secured a spring member 47 which takes up considerable lost motion and insures the positive returnand retraction of the tool and turret slide 16 as well after the forward movement thereof. Each of the rods 42. 43. 44 and .46 are provided with suit able unions upon their free endsor adjustable buckles 48 to which are secured other actuating-rod members which have been indicated by thesame numerals since each pair of rod members and connections constitute a complete actuating means.

The invention consists of means for actuating the rods hereinbefore described in timed relation with each other by means of an attachment. which attachment may be secured tothe lathe if desired, as by means of the brackets 49 oininay be independently positioned therefrom The attachmentcomprises a main actuating wheel or disk 50 rotatabl v supported in the frame 5].. which is in turn supported by the standards 52. The wheel 50 is rotated, see F igs. 1 and 2, by means of the gear teeth 53 formediupon the external periphery of the wheel. Meshing with the teeth 53, which constitutes aworm wheel, is a worm member 54 suitably secured to a shaft 55 supported in the housing member 56. The shaft 55 cooperates with adriving shaft 57 by means of a slot and .ttvely. Associated with each shifting the clutch frame in any suitable manner.

pin connection 58, the pin being designated by the numeral 58. The pin 59 may be retracted or withdrawn at pleasure such that the power mechanism associated with the shaft 57 is disconnected from the actuating wheel 50 and said shaft may be rotated by means of the squared end 60 and the usual handle means not shown.

l Vhen the pin 59 is associated with the clutch or drive connection 58, as illustrated in Fig. 2, the same is actuated by means of the shaft 57. The means for driving the shaft 57 comprises a cone pulley 61 mounted upon the shaft 62. Associated with the pulley 61 and shaft 62 isthe clutch dog; 63 and clutch cone .64 shiftable by means of the clutch rod 65 into and out of operative position. The shaft 62 is thus rotated by means of the clutch connection described and upon said shaft is secured a pair of different sized pulleys 66 and 67 respectively. The belt means 68 connects the pulleys 66 and 67 with the pulleys 68 .and 69 respectively, said pulleys being rotatable upon the shaft 57. Each of the pulleys 68 and 69 is provided with a suitableclu'tch face 70 and 71 respecof the clutch faces 7 O and 71 are the clutch faces 72 and 73 respec tively,.said clutch faces being slidable upon the shaft 57 and being rotatable therewith by being keyed or otherwise suitably secured .thereto. Each of the clutch faces 72 and 7 3 is provided with a shifting bracket 74 suitabl secured to a shiftin rod 75. The

rod 75 is actuated :bymeans hereinafter to be described in detail which is associated with the main actuating wheel 50. Therefore,-sa1d wheel controls its oi n rotating movement. It will be thus understood that when the clutch face 72 is associated with the clutch face 7 0, power is applied from the cone pulley 61 through which the pulley 68 and the worm 54 will be rotated at, what may be termed, the slow speed. Similarly when power is transmitted from the pulley 61 to the pulley 69 and thence to the shaft 57 through the clutch faces 71 and 73, the worm 54 will be rotated at a greater speed.

The rod 75 is provided with means for faces 72 and 73 into either of the fast or slow driving positions or to the neutral position. The means for shift ing the rod 75 to the two first mentioned positions comprise, see Figs. 1,2 and 3, a

pivoted lever 76, one end of which is secured to the rod 75 and the other endof which is .associatedwith a spring mechanism 77. said lever being pivoted intermediate its end at 78to albracket 7 9 secured to the supporting The pivot 78 comprises a rock shaft and upon the other end thereofis positioned a lever 79, which lever issecuredto said shaft intermediate its ends. To each of. the ends of the lever 79 is secureda link member 80. One link member is connected at its opposite end to a tripping lever 81 pivoted operatively upon the bracket 79 at 8L. Similarly the other link member 80 is pivoted at one end to a tripping lever 83, said lever being pivoted intermediate its ends upon the pivot 82. It will be understood that the levers 81 and 88 project inwardly towards the actuating wheel 50 andare positioned adjacent said wheel, the lever 83 lying close to the wheel and the lever 81 being positioned adjacent the lever 83. Suitable means are associated with the tripping levers 81 and 83, whereby the rod 7 5 may be actuated from one position to the othersuch that the wheel 50 will be rotated at either speed in the direction of the arrows as indicated in Fig. 2. As shown in Figs. 5 and 6, the means for tripping the levers 81 and 83 comprise the buttons 84: and 85 respectively.

The buttons 84; and 85 are dissimilar and project from the face of the wheel 50, as shown in Fig. 6. Thus the button 85 is of substantially one half the height of the button 8& and is adapted therefor only to actuate the lever 83. The button 8 1 is provided with a cut-away portion 86, which cutaway portion permits the free end of the tripping lever 83 to pass the same without lnterference. The lever 84c therefore is adapted to engage the outermost tripping lever 81 and actuate the same. It will be understood that'the spring means 77 illustrated in Fig. 7 is adapted to tilt the lovers 79 and 76 from the neutral or central position into one or the other of the actuating positions. Thus the pin 8a or 85 tilts the espective lever to actuate the rod 75 and the spring means 77 carries the mechanism over center so that the other tripping lever is positioned for subsequent operation.

The means for actuating the several rod members 42, 43, stand 16 comprise suitable means positioned upon the main actuating wheel and other means associated therewith and actuated thereby, said other means including means for providing a reciprocatory motion, which reciiprocat-ory motion is transmitted to the rod members to reciprocate the same and actuate the several lathe mechanisms associated with said rod members 12, a3, and 4:6. Reference will now be had in particular to Figs. 2 and The rod 12 is adjustably secured at its free end to a lever 87, which lever is pivoted at 88 to a bracket 89 suitably secured to and forming a part of thei rame of the attachment. 1n the present instance the bracket 89 is continued upwardly and supports the housing member 56. The rod member 12 is secured to the lever 87 in any one of the adjusted positions, as illustrated. Intermediate the pivot'88 and connecting the rod %2, 1s secured a connecting rod 90 to which is pivoted a block 91 reciprocatorily mounted upon a slide 925. The slide 92 in the present instance is shown formed integral with and forms a part oi the 'l'ramc rotalably sup porting the main actuating wheel. Upon the inner face of the slidablc block 9! is rotatably supported a suitable cam rollcr or follower 93, shown dotted in Fig. .4, which roller is actuated by suitable cam moans Ellpositioned upon the main actuating wheel 50. Thus the cam members or cam means 91 reciprocate the slidable block 91, which in turn reciprocates the rod lo move the cross slide 13 transversely of the machine and into and out of engagement with the work 3&1. As shown clearly in Fig. 2, the wheel 50 is rotated at the slow speed through the norm 5%. By means of a button 84-, when the same is moved into engagement with the lever 81, the wheel will be rotated at an increased speed and at the same time the cam means 9-1 will have moved the roller outwardly and radially from the center of the wheel, thereby moving the rod 12 towards the left of the lathe thereby actuating the slide 18 and moving the tool 14-.

transversely of the work and lathe. The wheel is rotated at high speed until. the button 85 positioned adjacent the tripping levers 82-3 whereupon the speed of rotation is again changed by said button 85 to the slow speed condition.

Similar to the foregoing construction, the rod a3, which controls the sell. centering and quick acting chuck 26 is adjustably secured to the lever 95. One end of the lever 95 is pivoted at 90 to a supporting bracket 97 which, in the present instance, extends upwardly and forms a bearing 98 for one end. oi the shaft 57. Intermediate the pivot connection 96 and the connection with the rod all there is pivoted one end 01 the connecting rod'99, the other end of which is pivoted to a block 100 which block is slidable upon suitable slide 101 which, in the present instance, is formed similar to the slide 92. The block 100 is also similar to the block 91 and is similarly provided with a cam follower 102, which cam follower is actuated by a series of cams or cam means 103 which cam means may be associated withv the laces 8-1: and 83 similar to the cam means 91 hcrcinbclore described, whereby said parts all are actuated in timed relation with each other.

Upon the opposite side oi the main actuating wheel 50 is positioned the back gear control rod 14:, said rod terminating at 101 and being adjustably SOCUIOd to one end ol" the pivoted lever 105, which lever is pivolcd intermediate its ends at 100 to the upwardly projecting bracket 97. the lover 105 is connected to a connecting rod 107 which rod is pivoted to a block 108 slidably mounted upon a slide 109, said slide 109 being preferably formed integral with the means rotatably supporting the master The other end of i weaves wheel 50. On the block 108 is secured the cam roller or follower 110 which roller is actuated by suitable cam means 111 positioned upon the plate 50.

'lhe turret slide control rod +16 is adjustably connected to a lever 112 at 113, said lever being pivoted intermediate its ends at 114: to a bracket 115 substantially similar to the bracket 89. The other end of the lever 112 is connected to a connecting rod 116 in turn connected to a slidable block member 117, which block member carries upon its inner face substantially similar to the pre vious mentioned slidable block members, a roller orcam follower 118 which is adapted to be actuated by the cam means 119 secured upon the face of the revolving plate 50.

While the cam means associated with the rod members L2, 13, 41-4 and 45 for actuating the same are shown in the several figures and in particular in Fig. 1:, as comprislng a plurality of cam surfaces, said cam means DNLYCOHSlSl] of suitable channels adapted to receive by the several cam rollers. P referably, however, the cam means are composed of several parts such that the same may be adjusted relative to the plate member and to each other. For this puriose the plate or main actuating wheel provided with a plurality of concentric series of holes 550 in which the various cam blanks may be adjustably secured. It will, of course, be understood that since the turret lathe to which this invention has been applied consists of a six tool turret, said wheel necessarily is divided into at least six central angles each of which constitutes a period of operation coinciding with. the period corresponding to one of said turret tool pos1- tions. Thus with a two tool turret piece of work or a three tool piece of work, the cycle of cumming necessarily will be triplirated or duplicated respectively upon both faces. 1

In order to insure that the lathe in the prcsentinstance or the machine to which theiiwention is applied, will operate at Illl1X imum eiiiciency consistent with the capacity of the maritime the speed of the master wheel is regulated so that at certain periods of operation said wheel is rotated faster than at other periods during a complete revolution. lltwill be remembered that the pins 8% and 85 are positionedupon the periphery of the master wheel 50 so as to trip the tripping levers 81 and .lt Wlll, therefore, be .understoorjl that when a plurality of said pins is pivoted upon the periphery of said master wheel, asshown the drawings: and in particular Fur. 4-, said master wheel, during the variousperiods comprising one revolution, may be xllltml'l' llttent-ly actuated at either the slow or speed. Thus the tool which is to operate upon the work is the determining factor which governs the speed at the particular instant. Also, while the turret toolis being withdrawn, after said tool has been disengaged fron'i the work, the cross slide may be actuated simultaneously therewith to position the outer forming tool or cutting-off tool ready for the forming or cutting-off work. Both of these operations can be simultaneously executed at the high speed thereby increasing the eiiiciency of the lathe. It will, of course, be understood that it necessary the actual forming orcutting-olf movement upon the stock may be executed at slow speed.

lVith the foregoing arrangement of the parts it will be understood thatthe sequence of operations is as follows. The self centering-chuck is actuated to release and feed the stock into the lathe and simultaneously therewith the turret is actuated to position the stop tool. adjacent the stock and thereby limit the forward movement of the same.

During the clamping operation of the self centering chuck the turret is retracted at high speed from its position adjacent the work and at the end of said stroke said turret isrotated bythe mechanism internal to the turret, thereby positioning the next tool in position. Simultaneously with the retraction oft-he. turret hereinbefore mentioned, the cross slide may be actuated and the exterior surface of the stock machined. The cross slide and machining tool is then retracted and, ifdesired, simultaneously therewith .the secondmentioned tool in the turret is brought up into engagement with the work, both of these movements being executed. at what is known as high speed, since no work is being. performed upon the stock. The turret tool then operates upon the work and, it necessary, at the slow speed, said tool after finishing this operation, such as for instance drilling, is retracted at high speed and another tool such as a reamermay be positioned also at high speed adjacent the work and may operate upon the stock at slow speed. if necessary. If the reaming constitutes the last operation upon the stock said turret may be retracted at high speed and simultaneously therewith the cross slide may be moved transversely of the stock and lathe (also at high speed) until the cutting off tool is positioned adjacent the work and, if necessary, said tool maybe projected into and upon the work at slow speed until the completed work is severed from the stock. The cutting-off tool is then retracted at highspeed and simultaneously therewith the stop tool. hereinhefore described as the first step in the cycle, may be brought up adjacent the selfcentering chuck whereupon when the stock is fed through and by said chuck,,the cycle is again completed.

From the foregoing); it will be understood that after the cams have been adjusted to the various operations to be performed, said machine automatically controls the operation of the lathe or other similar machine to which the invention has been applied such that no further attention is required to operate said machine or lathe at its maximum efficiency, except to insure that sufiicient stock is supplied to the self centering chuck and that the several tools which actually perform the work are maintained in the proper condition.

It will be understood that after the tools have been adjusted and the timing thereof adjusted, by means of the plurality of concentric holes adapted to receive the several cam means hereinbefore described, said attachment machine willbe infallible in its operation so far as its operation is concerned, but it will be understood that should for any reason any mishap or accident occur to the tools associated with the lathe or in the lathe itself, the invention will still continue to operate except as now noted. If any portion of the lathe should refuse to function or any of the tools become jammed, either with respect to the tools or with respect to the work, said ja1nming'will automatically, see Fig. 2, shear the pin 59, whereby the shaft 57 will continue to rotate without rotating the shaft 55 and, therefore, the wheel 50 will remain idle.

Another feature of the invention associated with the pin 59 and the notched shaft end 60 hereinbefore described, is that the master wheel 50 may be manually rotated at any desired speed which permits the operator to adjust the eamming of the attachment more accurately than would be possible were the same to be power driven during the starting up or adjusting period.

In certain work it is necessary to take certain pieces of work which previously have been operated upon as described and position the same in the chuck and then continue to operate upon the work positioned in the chuck. This class of work is technically known as chuck work and by means hereinafter to be described this machine makes it possible to automatically operate upon such classes of work with a minimum amount of manual control.

This semi or substantially entire automatic control, it will be understood, requires that the lathe or machine to which the attachment is being applied be stopped and that the attachment or master Wheel 50 also be stopped at a predetermined point in the cycle of operations. To insure that the attachment and lathe will be substantially automatic in its operation it will, of course. be understood that it is necessary to simultaneously actuate the lathe and the attachmen. When the attachment is thus used with the lathe it will be understood that the rod 43 is disassociated from the lever 27 so that the chuck 26 or an equivalent chuck may be manually operated by the operator to receive the work as indicated.

The means for automatically stopping the lathe and attachment when the work in the chuck has been finished, and for automatically starting said attachment and said lathe after a piece of work has been manually positioned within the chuck is as follows. It will be remembered that the handle 21 controls the power supplied to the lathe. Secured to the handle 21. is a horizontal bar 120. The other end of the horizontal bar 120 is connected to one end. of the lever 121., said parts as shown in Fig. 3 being illustrated in the forward driving position only when the clutch member 20 is in engagement with the dogs 19. whereby the pulley 18 may rotate the shaft 22. see Fig. 1.

The parts are shown in Fig. 1 to be in neutral position, while the same parts are shown in Fig. 3 in the forward driving position. The lever 121 is pivoted at 122 to a bracket formed upon the upwardly ex tending bracket 115, and said lever upon its other end 123 is provided with a cam roller 12%, said roller being actuated by suitable cam means 125. Midway between its upper end and the pivot 122 is formed an offset portion 126, which offset portion is adapted to receive an elongated dog or latch 127. said dog being pivoted, as shown in Fig. 8, by means of the pin 12% and tor minating in a tapered face 129 which face and elongated body portion is slotted .as at 130 for a purpose hereinafter to be described. It will. be understood that when the edge 131 is arcuately formed thereby permitting the latch 127, when desired, to be rotated 180 degrees into the nonactlniting position. hen thus positioned the device hereinafter to be described is rendered inoperative and it will be understood that the cam means 125 associated with the lever is also removed from the main actuating wheel 50.

The means associated with the elevating dog or latch 127 is shown clearly in Figs. 3, 7 and 8. A collar member 132 is secured to the rod by suitable means, such as a set screw 133. The rod 75 is shown clearly in Figs. 3 and 7 as slidably supported in the brackets 136 and 137 formed upon the up wardly extending brackets 11:) and 97 respectively. Positioned above the collar 132 and adjacent the lever 121 and beneath the angular portion 126 is a cylinder 13S supported u eon the bracket 115 by the portion 139. itliin the cylinder 138 is av plunger or pin member 1 10 suitably cut away at 1 -11 to receive and seat a spring memher H2. which spring member normally forces the plunger 140 downwardly and into engagement with the collar 132 to lock said collar beneath the cylimler 13F; and lock the clutch l t) t) llitl in Fig.

members 72 and 73 in the neutral position. The pin member 141 extends upwardly over the cylinder 138 and is provided with a head portion 1. 1-3,which head portion and body portion 144 is adaptedtobe associated with the tapered and slotted tooth 127 so that when the parts are in the forward driving position as illustrated in Fig. 3 and the master wheel is rotated slowly, said tooth maintains the pin member 140 out of engagement with the collar 132. The bar 120 is moved to the neutral position, illustrated 1, by the lever 121 pivotedat 122, which is moved to the right of said figure to release the pin member 140 to the action of the spring 1 12 so that said pin member is adapted to engage in the groove 132, and due to the action of the spring 77, shift the rod 75 to the neutral position. If the clutch 73 were driving, the parts would be positioned substantially similar to that shown in Fig. 3 except that the collar 132 would be positioned to the right of the pin 140 instead of to the left, as illustrated, and when said pin was released said collar would be moved from the right of the pin to beneath the pin instead of as shown in Fig. 3 from'the left of the pin to beneath the pin. A pin member 145 associated with the plunge- 140 and cylinder 138 is adapted to maintain and lock the plunger in the nonseating position when the latch 127 is moved tothe non-actuating position by being seatable in the registrable openings 146 and 14-7 respectively. It will be understood that the lever 121 is actuated by the cam means 125 and roller 124: to automatically stop boththe lathe and the attachment simultaneously when the work has been completed, and the lathe or similarmachine is then adapt ed to receive another piece of work.

It will be understood that the bar 120 is manually actuated after a piece, of work has been positioned in the chuck 26 and when so positioned said tooth 127 engages-i the pin 1. 10 and elevates the same from the collar 132, whereupon said rod 751s released to the action of the spring member 7'7 and the clutch l'lereinbefore in engagement is again returned to engagement such that the attachment again is rotated and the lathe is likewise rotated'and controlled.

While the cam member 125 has been described as of just suificient size to move the lever 121 to the neutral position,it will be understood that a plurality of siiitalily sized cam buttons 125 see l, may be used to actuate the follower 1241: and the lever'121. In this arrangement it will be understood that the latch 12'? is maintained in the non-actuating position and the plunger 140 is maintained by the pin looking member 14?) in the elevated position. The cam means 125 is thus adapted to shift the lever 121 from the forward driving WM-Ml All position in the reverse driving position. This feature of the reverse driving of the lathe is essential when a piece of work has to be tapped out or cut with a die to pro vide either an internal or external thread thereon. The attachment, of course, continues to be actuated during the foregoing operation.
